I am finally making that leap of faith as I change from a HOB filter on my 27gal to a canister filter. I am going to be purchasing the Eheim 2215 kit: Classic Series Canister Filter > 2215 Plus Kit
but am not a fan of the carbon pads since they need to be replaced at the very most every month. Can I just leave it in the canister as added mechanical filtration or should I replace it with another blue mechanical pad? I know many of you have had great success on using different media with different proportions. If you look at the media tab (in the link above) does that sound ok?
As always, any input welcomed,
